本発明は磁気ディスク装置におけるフレキシブルプリン
ト板の支持構造に係し、特に、このプリント板を支持す
る支持板の形状及び、アクチュエータ本体への装着構造
に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a support structure for a flexible printed board in a magnetic disk drive, and particularly relates to the shape of a support plate that supports this printed board and its attachment to an actuator body. Regarding structure.
磁気ディスク装置のアクチュエータ本体へのフレキシブ
ルプリント板の装着に関しては、例えば特開昭６１−２
４２３８２号公報に記載のように、フレキシブルプリン
ト板の可動部が常に屈曲した状態になっているものがあ
る。Regarding the attachment of a flexible printed board to the actuator body of a magnetic disk device, for example, Japanese Patent Laid-Open No. 61-2
As described in Japanese Patent No. 42382, there is a flexible printed board in which the movable part is always bent.
上記従来技術はフレキシブルプリント板のアクチュエー
タ上に装着された部分の振動については考慮されていな
い。The above-mentioned conventional technology does not take into consideration the vibration of the portion of the flexible printed board mounted on the actuator.
その為、アクチュエータが動作したとき、アクチュエー
タ上に装着されたフレキシブルプリント板及び該フレキ
シブルプリント板の支持剛体板が振動し、セトリング、
オフトラック悪化の原因となる。Therefore, when the actuator operates, the flexible printed board mounted on the actuator and the supporting rigid plate of the flexible printed board vibrate, causing settling and
This will cause off-track deterioration.
また、フレキシブルプリント板をアクチュエータに全面
あるいは大部分の面が接触する構造の場合、振動を抑す
ることはできるがフレキシブルプリント板上に実装した
電子部品から発生した熱が、。In addition, in the case of a structure in which the entire or most of the surface of the flexible printed board is in contact with the actuator, vibration can be suppressed, but the heat generated from the electronic components mounted on the flexible printed board can be suppressed.
アクチュエータに伝わり易くなり、サーマルオフトラッ
クの原因となる。This can easily be transmitted to the actuator, causing thermal off-track.
本発明の目的は、フレキシブルプリント板及び支持板の
振動による影響を防止しセトリング、オフトラックの性
能を向上することにある。An object of the present invention is to improve settling and off-track performance by preventing the effects of vibration on a flexible printed board and a support plate.
上記目的を達成する為に、本発明はフレキシブルプリン
ト板の支持板の少なくとも一辺に折曲げ部分を設けこの
支持板を介してアクチュエータに装着したものである。In order to achieve the above object, the present invention provides a flexible printed board with a bent portion on at least one side of a support plate and is attached to an actuator via this support plate.
この様に、少なくとも一辺に折曲部を設けたフレキシブ
ルプリント板の支持板は、折曲げを設けない支持板に比
べて、高い剛性が得られ、良好な振動特性が得られるの
で、セトリング、オフトラックの性能を向上させること
ができる。In this way, a support plate for a flexible printed board that has a bend on at least one side has higher rigidity and better vibration characteristics than a support plate that does not have a bend. Truck performance can be improved.
また、本発明に係る支持板は少なくとも２つの異なる方
向にてネジ締結してアクチュエータに装着されるので、
−層振動が防止できる。Furthermore, since the support plate according to the present invention is attached to the actuator by screwing in at least two different directions,
- Layer vibration can be prevented.

。In FIG. 1, a plurality of head assemblies 5b including magnetic heads 5a are fixed to the actuator body 3. As shown in FIG. A coil 6 is attached to the rear end of the actuator body 3, and driven by the coil 6, the body 3 is rotatably supported via a bearing 7. An electronic component 8 is mounted on the flexible printed board 1, and this is mounted on the support plate 2.
It is attached to the actuator main body 3 via. here,
The actuator body 3 has four flexible printed boards l attached to a support plate 2 provided with bent parts 2a and 2b.
The actuator main body 3 and the support plate 2, which are fastened together by real screws 4, have two contact portions 9 (hatched portions), and two fastening screws 4 are fastened in different axial directions.
一方、上記のような折曲部分２ａ、２ｂを持たない支持
板を想定すると、これは面に垂直な荷重に対して剛性が
低く、特に面に垂直な方向は、アクチュエータの回転方
向と一致するので、振動が発生し易い。On the other hand, assuming a support plate that does not have the bent portions 2a and 2b as described above, this has low rigidity against loads perpendicular to the surface, and in particular, the direction perpendicular to the surface coincides with the rotation direction of the actuator. Therefore, vibration is likely to occur.
第２図の（Ａ）は本発明を適用しない支持板に折曲が無
い場合と有る場合の、面に垂直な荷重に対するたわみ量
を示す。これに対して（Ｂ）の如く本発明の折曲げ２ｂ
の有る支持板の方が剛性が高いことがわかる。FIG. 2(A) shows the amount of deflection against a load perpendicular to the plane when the support plate to which the present invention is not applied has no bends and when the support plate has bends. On the other hand, as shown in (B), the bending 2b of the present invention
It can be seen that the support plate with has higher rigidity.
また、第１図の４ａ、４ｂのようにネジの締結方向を複
数持つことは、多くの方向の振動に対して剛性を持つこ
とができる。Further, by having a plurality of fastening directions of the screws as shown in 4a and 4b in FIG. 1, it is possible to have rigidity against vibrations in many directions.
本発明によればフレキシブルプリント板の支持板の少な
くとも一辺を折曲げて装着する様にしたので剛性が高く
なり、セトリング、オフトラックの性能を向上すること
ができる。According to the present invention, since at least one side of the support plate of the flexible printed board is bent and attached, the rigidity is increased and the settling and off-track performance can be improved.
